title: [Female sex behavior of male rats castrated at birth and given female sex hormones: effects of hour of castration].
abstract: Female sexual behaviour of male Rats castrated at birth and treated with female sexual hormones: effects of hour of castration. Male Rats castrated at 0 hr and injected with aestradiol and progesterone as adults display a typical female sexual behaviour. The probability of them showing the lordotic reflex is significantly lower when castration is performed at 6 or 12 hrs. This result suggests that, during the 6 first postnatal hours, Rats testes could influence the adult sexual behaviour.
